Olds Performance Products pistons

What do you all think about these for a mild Olds 350 build? '68 350 with 1971 number 7 heads.

Looks like old school 5/64" ring pack, unknown dish and the joy of dealing with Andy Miller.

Ask Bill Travato and Paul Tester that question. Surprised he used a 5/64" ring pack on these pistons.

Yeah, so far oil usage from these rings. No issues from the 1.2mm in my Challenger's 3.6 Pentastar either. With the Mahle 10.2cc dish pistons Cutlassefi sells, you will get low to mid 9's compression. The pistons will be less than .020" below deck. My block needed a .016" cut. My pistons ended up .002" or .003" below deck with my rough measurements.

I heard a tidbit about Andy Milltard about some guy in Ohio that wanted to kill him. He screwed him on a set of pistons or something. Mid 2000's. The guy's name was Rick and just got out of jail. Anybody know or remember the full story?

I don't deal with Andy, he's just had some fast Oldsmobiles, fact. As far as sticking with Chevrolet, I'd like too, but they keep pulling me in. Now since I've wondered for some time now: Did you ever get your engine finished, and if so, what were the results?

If you’ve never dealt with Andy, then why would you recommend him, solely on his car? That’s not a good way to go, there are lots of manufacturers that can’t stand dealing with Andy for various reasons. He’s a douche bag, knowledgeable or not.
The bad Mondello (Lynn) was knowledgeable too, and had a fast car. But he ripped off everybody and their brother, well documented. Would you have recommended him too?
If you don’t know, don’t post, please.

This is why I came here to ask. I have dealt with some jerks over the years, and don't want to add to the collection.

I never recommended him for anything, I just stated he knows his way around an Oldsmobile, his skills far surpass yours for that matter, but I can't say I don't care for the guy myself, but skills are skills, you don't take that away from the guy because you don't like him. Lynn Mondello NEVER did anything at a drag strip, Andy has. A engine builders drag strip performance is a great indicator of what a engine builder can do for you.

You are so wrong in so many ways!! About Andy! You have no idea how bad a engine builder he really is!! I doubt he built his drag engine on his own. Do a little research!

You spreading rumors. A friend of mine in Phoenix just built a engine with parts supplied by Andy and there was not a problem.

Things can happen, it's how you deal with them after the problem. What else you got?

Your friend built it, ANDY didn’t. So how does that prove Andy’s a good builder?
We all know you have an ax to grind with me personally, consequently your comments got the response from others they deserved.
Have a nice day.

OP, you don’t have to come to me, but RUN don’t walk the other way from Andy.

Baffling how someone can tell excatly what the ring grooves are by looking at a picture, unless they are here to spread dis-information. The piston pictured is a CP piston that will hold a 1/16th, 1/16th, 3/16th ring package.

You are so wrong in so many ways!! About Andy! You have no idea how bad a engine builder he really is!! I doubt he built his drag engine on his own.
More dis-information from the peanut gallery. Fully equiped shop and 42 years of building engines. Some pretty darn fast ones at that.
Check out Olds Performance and Machine on youtube.

How about one, overboring a Nascar DX block. That failed on the dyno.
More dis-information spread by the peanut gallery.

In 1988 at a prior 384 cubic inches, a non nascar block of our own, not a customers, was taken an additional .015 per side and during the beginning of the dyno session we shut it down. Disasembled and yes a small hole the size of half a dime was present one inch down on one bore. Race season of 1987 the engine was bracket racing every weekend with a best of a 8.98@149mph. Almost 40 years ago.

No issues from the 1.2mm in my Challenger's 3.6 Pentastar
A pentastar, an LS, a small block chevrolet and many other manufactures blocks are not that of an Oldsmobile. If you are targeting a max hp number on a dyno and could care less about oil consumption, then many of these so called light ring packages will give you just that. You have to clearely understand how these Oldsmobile engine blocks are designed. The structure and integretity. With an equiped shop and running a ck10 or cv 616, deck plates on and deck plates off, you truely get to understand the amount of bore distortion these Oldsmobile engine blocks have, and they shouild never be compared to any other manufacture. We see plenty of Olds engines with these trick low drag ring packages, and they consume oil. You can tell immediately in the exhaust port color how an engine is doing. Soo many factors that go into ring choice. You will not find a piston company or a ring manufacture working R&D with an Oldsmobile engine. A bore is not a bore, as integrity plays a huge factor.

Not only do we work on Oldsmobile blocks, we get to see exactly how they differ from other manufactures. Here is small block Chevrolet.

Going off your description on YOUR site Andy. Maybe update it and include the dish size too. Oh and quite a few of us have the Mahle 1mm/1mm/2mm piston rings you said would not work. Zero oil burning, so far for me. Two over 400 HP and nearly 500 ft-lbs. Three different builders and two different dyno's. With the new Edelbrock heads and roller cam swap this Winter, I should be close to the 400 HP mark, plenty for me in a 55 year old 4 wheel drum brake car.
